Getting Better All the Time?

From David E. Nye, American Scientist

Whether it’s intended to be so or not, the title of Kevin Kelly’s What Technology Wants is a provocation to most historians of technology, who would reply almost unanimously that technology has no wants or desires. Each tool or machine has latent uses, but each is only an inert object until human beings decide whether and how to use it. In contrast, Kelly talks about technology as a composite whole that emerged before human beings existed and that facilitated their rapid domination of the planet. For him, technology has intentions, and it is radically accelerating evolution.

Kelly has been thinking about technology for most of his life, first as a backpacker wandering the Third World, later as one of the pioneers of what became the Internet, and finally as one of the founders and editors of Wired magazine. He overcame his early suspicion of Western technology largely as a result of his encounter with interactive computer technologies. He was one of several in the counterculture to move from working on the Whole Earth Catalog to celebrating the Internet as a new online facilitator of grassroots movements.

Mind vs. Machine

From Brian Christian, the Atlantic

In the race to build computers that can think like humans, the proving ground is the Turing Test—an annual battle between the world’s most advanced artificial-intelligence programs and ordinary people. The objective? To find out whether a computer can act “more human” than a person. In his own quest to beat the machines, the author discovers that the march of technology isn’t just changing how we live, it’s raising new questions about what it means to be human.

Brighton, England, September 2009. I wake up in a hotel room 5,000 miles from my home in Seattle. After breakfast, I step out into the salty air and walk the coastline of the country that invented my language, though I find I can’t understand a good portion of the signs I pass on my way—LET AGREED, one says, prominently, in large print, and it means nothing to me.

I pause, and stare dumbly at the sea for a moment, parsing and reparsing the sign. Normally these kinds of linguistic curiosities and cultural gaps intrigue me; today, though, they are mostly a cause for concern. In two hours, I will sit down at a computer and have a series of five-minute instant-message chats with several strangers. At the other end of these chats will be a psychologist, a linguist, a computer scientist, and the host of a popular British technology show. Together they form a judging panel, evaluating my ability to do one of the strangest things I’ve ever been asked to do.

I must convince them that I’m human.

Fortunately, I am human; unfortunately, it’s not clear how much that will help.

The Memristor

From Brian Hayes, American Scientist

When Bell Telephone Laboratories announced the invention of the transistor in 1948, the press release boasted that “more than a hundred of them can easily be held in the palm of the hand.” Today, you can hold more than 100 billion transistors in your hand. What’s more, those transistors cost less than a dollar per billion, making them the cheapest and most abundant manufactured commodity in human history. Semiconductor fabrication lines churn out far more transistors than the world’s farmers grow grains of wheat or rice.

In this thriving transistor monoculture, can a new circuit element find a place to take root and grow? That’s the question posed by the memristor, a device first discussed theoretically 40 years ago and finally implemented in hardware in 2008. The name is a contraction of “memory resistor,” which offers a good clue to how it works.

Memristor enthusiasts hope the device will bring a new wave of innovation in electronics, packing even more bits into smaller volumes. Memristors would not totally supplant transistors but would supplement them in computer memories and logic circuits, and might also bring some form of analog information processing back into the world of computing. Farther out on the horizon is a vision of “neuromorphic” computers, modeled on animal nervous systems, where the memristor would play the role of the synapse.

Facebook 2, Arab leaders 0

From Sarah Firisen, 3 quarks daily

“Facebook 2, Arab leaders 0”, read a sign held by an Egyptian woman on Friday as the celebrations erupted in Tahir Square. In a sharply ironic turn of events, it seems that American software companies may have done more to bring about regime change in the Middle East than all the trillions of dollars poured into the wars in Iraq and Afghanistan and the resulting deaths and casualties. There does seem to be no doubt that Facebook, Twitter, and YouTube had a significant role to play in giving a voice to the democracy-seeking citizens of Egypt & Tunisia and helping them to create a community of international supporters. If there ever is a judgement day, surely Mark Zuckerberg’s sins of inflicting Farmville and Mafia Wars on the world will be more than outweighed by the events of the last month of so.

And this makes me wonder, will people now stop saying that they don’t see the point of social media and that it’s an absurd waste of time? Of course, many of the things that people choose to spend their time doing on social media – see above comments re: Farmville and Mafia Wars – may not be the most productive things they could be doing. But, the same is true for almost everything; the fact that some people spend their time reading Harlequin romances, doesn’t negate the value of reading in general.

Drumming Up More Internet Addresses

From Laurie J. Flynn in The New York Times:

Who could have guessed that 4.3 billion Internet connections wouldn’t be enough?

Certainly not Vint Cerf.

In 1976, Mr. Cerf and his colleagues in the R.& D. office of the Department of Defense had to make a judgment call: how much network address space should they allocate to an experiment connecting computers in an advanced data network?

They debated the question for more than a year. Finally, with a deadline looming, Mr. Cerf decided on a number — 4.3 billion separate network addresses, each one representing a connected device — that seemed to provide more room to grow than his experiment would ever require, far more, in fact, than he could ever imagine needing. And so he was comfortable rejecting the even larger number of addresses that some on his team had argued for.

“It was 1977,” Mr. Cerf said, in an interview last week. “We thought we were doing an experiment.”

“The problem was, the experiment never ended,” added Mr. Cerf, who is the chairman of the Internet Corporation for Assigned Names and Numbers, or Icann, a nonprofit corporation that coordinates the Internet naming system. “We had no idea it would turn into the world’s global communications network.”

2011 Technology Conference – Evening Tour of the Guggenheim Bilbao

Please join us on a guided tour of the world famous Guggenheim Bilbao Museum. In addition to the permanent collection we will see Chaos and Classicism: art in France, Italy, Germany and Spain, 1918-1936. Chaos and Classicism, which opens this fall at the Solomon R. Guggenheim Museum, New York, concentrates on the classical aesthetics that appeared in the wake of the devastation wreaked by World War I. The exhibition examines the period between the wars and the work of the leading artists of the day in France, Italy, and Germany: the poetic dreams of Antiquity of the Paris avant-garde that featured Fernand Léger and Pablo Picasso; the politicized renaissance of the Roman Empire under Benito Mussolini, with artists like Giorgio de Chirico and Mario Sironi; the functionalist utopianism of the Bauhaus and the classicism at the service of the exaltation of the Aryan race under the incipient National Socialist regime in Germany, with artists like Oskar Schlemmer and Otto Dix. Accompanying the presentation at the Guggenheim Museum Bilbao will be a selection of works by Spanish artists to illustrate the situation in the run-up to the Civil War. Besides paintings, sculptures and photographs, the exhibition also looks at the architecture, film, fashion, and the decorative arts of the time.

Friday, 25 March 2011 6:30-8:00pm (18:30-20:00).  For more information visit our website.

Cyberspace When You’re Dead

From Rob Walker, The New York Times

Suppose that just after you finish reading this article, you keel over, dead. Perhaps you’re ready for such an eventuality, in that you have prepared a will or made some sort of arrangement for the fate of the worldly goods you leave behind: financial assets, personal effects, belongings likely to have sentimental value to others and artifacts of your life like photographs, journals, letters. Even if you haven’t made such arrangements, all of this will get sorted one way or another, maybe in line with what you would have wanted, and maybe not.

But many of us, in these worst of circumstances, would also leave behind things that exist outside of those familiar categories. Suppose you blogged or tweeted about this article, or dashed off a Facebook status update, or uploaded a few snapshots from your iPhone to Flickr, and then logged off this mortal coil. It’s now taken for granted that the things we do online are reflections of who we are or announcements of who we wish to be. So what happens to this version of you that you’ve built with bits? Who will have access to which parts of it, and for how long?

Not many people have given serious thought to these questions. Maybe that’s partly because what we do online still feels somehow novel and ephemeral, although it really shouldn’t anymore. Or maybe it’s because pondering mortality is simply a downer. (Only about a third of Americans even have a will.) By and large, the major companies that enable our Web-articulated selves have vague policies about the fate of our digital afterlives, or no policies at all. Estate law has only begun to consider the topic. Leading thinkers on technology and culture are understandably far more focused on exciting potential futures, not on the most grim of inevitabilities.

A Broadband Boom in the Boondocks

From Scott Woolley in Technology Review:

For a glimpse of the wireless future, take a look at the Yurok Indian reservation, an out-of-the-way spot just south of the California-Oregon border at the mouth of the Klamath River. There, among the giant redwoods, stand three new towers built to create a new type of wireless network, known as “super Wi-Fi.”  If the U.S. Federal Communications Commission gets its way, super Wi-Fi will become a key part of rural America’s digital infrastructure.

Most people living on the Yurok’s 63,000-acre reservation lack phone service. Almost none have high-speed Internet. The new towers aim to fix both problems. Unlike regular Wi-Fi networks, which are generally limited to beaming high-speed Internet around a house, super Wi-Fi promises to blanket entire neighborhoods with high-speed access.

A Yurok tribal spokesman says the new signals will reach even into the steep-walled valleys that play havoc with most wireless signals. They plan to start testing the system this week.

The FCC is so enthused with the idea of super Wi-Fi that it took the idea nationwide last month, issuing final rules that will free any town or county to do what the Yurok have done.  On Monday, FCC chairman Julius Genachowski proposed a way to pay for much of that infrastructure that would be needed to support municipal Super Wi-Fi. He wants to convert the current system of rural phone subsidies, which now total $8 billion a year, into a more modern system that can pay for things like super Wi-Fi.

Caught in the web

From Ben Hammersley. Financial Times.com

The internet has come a long way since Sir Tim Berners-Lee, the inventor of the world wide web, turned on the first web server in Geneva on Christmas day 1990. Today, 2bn people are online; 800m of them are on Facebook. Every minute, 24 hours worth of video is uploaded to YouTube. Google, a company founded only 15 years ago, has a market capitalisation just short of $200bn and a mission statement that it intends “to organise the world’s information and make it universally accessible and useful” – something no one thinks unlikely or even remarkable. We now bank, shop, communicate, work and date through the internet. The internet has come of age. It is as defining an achievement for humanity as the Enlightenment or the industrial revolution.

But as the web’s youthful potential and teenage brashness give way to a more grown-up, complicated and multifaceted personality, our reaction to it has also changed. Our enthusiasm is tempered by a realisation that it is not simply an exciting force for good, as it was first seen. This year’s opening salvo of books about the internet does not laud web entrepreneurs or predict jetpacks and digital utopia. Instead, Sherry Turkle’s Alone Together, Evgeny Morozov’s The Net Delusion and John Brockman’s collection of essays all soberly assess the current state of the internet and ask: are the changes the internet brings to our society and our human nature actually beneficial?

I first went online as a 12-year-old in 1988. The web had not yet been invented but by dialling into bulletin boards – message boards accessed by dialling a special number with a modem – I could join a tiny community of people who knew that they weren’t just going to change the world, they had invented a new one. In his 1994 book, The Virtual Community, Howard Rheingold, the writer and historian of the early internet, wrote of one of these new online worlds called “The WELL”: “There’s always another mind there. It’s like having the corner bar, complete with old buddies and delightful newcomers … except that instead of putting on my coat, shutting down the computer and walking down to the corner, I just invoke my telecom program and there they are.”

Following in the Footsteps of a Suburban Fisher

From the New York Times column “Scientist at Work”,

Today I drove down Central Avenue, the main drag between Albany and Schenectady, parked behind an industrial park, and ran into the woods. I was following the trail of a fisher my student, Scott LaPoint, named Klause. Scott downloaded the data from Klause’s GPS collar a few days ago, revealing where the animal had been the last month. Today I loaded these points into the map on my I-Phone and was now going to see if I could figure out why Klause found this little patch of woods so interesting.

This forest patch is only about 75 acres, and is bounded by an industrial park, the town dump, a neighborhood, and the Albany Pine Bush nature preserve across the railroad tracks. The GPS data show that Klause has spent a good part of the last month in here, but why?

I immediately see deer tracks as I run through the snow and into the woods; their sign is everywhere, there are A LOT of deer back in this little patch of woods. Fisher can’t kill deer, but they will feed on a frozen carcass for weeks.
